coughing and fever seem to be diagnostic differentiators — if you don’t have those symptoms, you probably don’t have flu. Check WebMD if you want. Their guys have been asking a zillion symptoms questions on the CDC update calls; and

you can not get swine flu from eating pork, just from the guy who makes your pulled-pork sandwich, so cover your mouths when you cough and wash your hands a lot.

Overall, the response seems quite proactive and will probably work as intended.
